There are several ways to do that. All of them require hardware that
is not commonly found today.

1) There was an 82442A module that allowed the HP-41 to print to the
82240A infrared wireless printer. If your PC is equipped with
suitable hardware, it can receive and decode the IR. There was
a product called "Hook-up" to do this, and there are also plans
to build your own receiver. The software for Hook-up, and the
free software for the build-your-own, might not work on modern
fast PCs. Also, this is a purely unidirectional transfer. If
you want to get data or programs from the PC to the 41, it won't
help.

2) If you have the 82442A, and also an HP-48, the HP-48 can receive
the IR printer signals, then send the data over a serial connection
to the PC. That avoids the problems with fast PCs.

3) You can use an HP-41 with an HP 82160A HP-IL interface, and an
HP 82973A HP-IL interface card in a PC with an ISA bus slot, and
various software that can talk to that card. Requires a PC with
an ISA slot, which is very uncommon these days, and reportedly
won't work with fast PCs.

4) You can use an HP-41, an HP 82160A, and an HP 82164A HP-IL to
serial converter connected to a serial port on a PC. I've found
this to be very convenient.

There are also HP-IL to parallel or IEEE-488 converters, and HP-IL
modems, any of which could be used with a suitably equipped PC.

5) (Possibly the easiest.) Write the HP-41 programs you want to transfer
to the PC onto magnetic cards, and send them to someone who has an
HP-41 with a card reader, and one of the above-listed setups. My
card reader is broken, so I can't offer to do that for you.
